Odd Science!! Monday, April 22, 2013Station 1- The Metalloids

Info: The metalloids have properties of BOTH metals and non-metals. On the periodic table, the metalloids are found between the transition metals and the non-metals. Metalloids are poor conductors of electricity. They are dull in appearance (no luster) and can crumble (brittle) pretty easily (not malleable or ductile). Metalloids are important, however, because all computers use metalloids to carefully control operations inside them (microchips)! Examples of metalloids include: Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Astatine, and Polonium (P) (find ‘em!).

“ Don ’ t front, Weathah Man! ” - Weather Fronts An air mass is a large body of air that has properties similar to the part of Earth’s surface over which it develops. For example, an air mass that develops over land is dry compared with one that develops over water. An air mass that develops in the tropics is warmer than one that develops over northern regions. An air mass can cover thousands of square kilometers. When you observe a change in the weather from one day to the next, it is due to the movement of air masses.

Atmospheric pressure varies over Earth’s surface. You may have heard a meteorologist on the news talk about high- and low-pressure systems. Remember that winds blow from areas of high pressure to areas of low pressure. As winds blow into a low-pressure area in the northern hemisphere, Earth’s rotation causes these winds to swirl in a counterclockwise direction. Large, swirling areas of low pressure are called cyclones or hurricanes and are associated with storm weather.

Winds blow away from a center of high pressure. Earth’s rotation causes these winds to spiral clockwise in the northern hemisphere. High-pressure areas are associated with fair weather and are called anticyclones. Variation in atmospheric pressure affects the weather. Low pressure systems at Earth’s surface are regions of rising air. Areas of low pressure usually have cloudy weather.

Consider what you learned about what happens to warm air when it rises higher into the atmosphere and gets cold. How does this explain why low pressure systems develop clouds?

Sinking motion in high-pressure air masses makes it difficult for air to rise and clouds to form. That’s why high pressure usually means good weather.

Why do high-pressure air masses sink?

A boundary between two air masses of different density, moisture or temperature is called a front. Cloudiness, precipitation, and storms sometimes occur around the edges of fronts. Three types of fronts include cold, warm, and stationary.

A cold front, shown on a map as a blue line with triangles, occurs when colder air advances toward warm air. The cold air wedges under the warm air. As the warm air is lifted, it cools and water vapor condenses, forming clouds. When the temperature difference between the cold air and warm air is large, thunderstorms and even tornadoes may form.

What is the effect of the mixing of cold and warm air?

Warm fronts form when lighter, warmer air advances over heavier, colder air. A warm front is drawn on weather maps as a red line with red semicircles.
